External podcasts might be the best place to catch up because Keith & Chemda have to explain themselves to people who haven't been regular listeners.
Best overview probably would be on
Tell The Bartender. Keith and Chemda go into more detail about the year's highlights - new relationships! Keith's dad is even weirder than you thought! - on
Beige Phillip &
Hot Mess Comedy Hour.
As for the show itself, there was a run of shows in California last year around the time of
Bert Kreischer's episode which I think shouldn't be missed. And they're hosting a whole other podcast with guests you'll recognize at
Starburns Audio.
